The aim of the study was an intercomparison of precipitation measurementswith classic (Hellmann) and automatic (tipping-bucket) rain gauges. Basing on theprecipitation data some agricultural factors were calculated. With the obtained results,prospects for automatic data use for agricultural enterprise were evaluated,along the homogenious series maintaining.The investigation was based on data obtained in years 2000-2004 fromclassic and automatic (Eijkelkamp) weather stations set in Mochełek near Bydgoszcz.It was supposed that in agrometeorological research the fundamental intervalof a factor is its ten-days value. Series of number from 15 to 180 (a ten-daysmeans in monts, seasons, warm and cold half-a-year and a year) obtained fromclassic and automatic measurements were compared. A particular consideration ofcorrelative results was done to assign mathematical formulas that would allow usethe Hellmann and tipping-bucket rain gauges data series exchangeably. ...
